Is 20W enough to fast charge my phone?

For most iPhones and many Android phones, yes. It will not hit the top speeds of 45W or higher chargers on newer flagship Android phones.

Can I charge two devices at the same time?

Yes, one on USB-C and one on USB-A. The 20W is shared, so each device charges more slowly than it would alone.

Does it come with a cable?

No cable is listed. You need your own USB-C or USB-A cable.

The input accepts 100-240V at 50-60Hz, so it works in most countries with the right plug adapter.

Is it safe to leave plugged in overnight?

It is ETL certified and shuts off automatically when a device reaches full charge.
